Hex key Proline 17 mm 48472 single-piece hex wrench

Proline 17 mm single-piece hex wrench 48472 is a solid, metric hex key designed for turning hexagonal fasteners in mechanical maintenance, assembly and repair tasks. The one-piece construction provides rigidity and consistent torque transfer, while the polished chrome finish improves surface protection and makes the tool easier to clean after use.

Advantages

The hardened and tempered steel construction ensures high strength and resistance to bending under load. A single-piece design eliminates joints that could fail and provides precise fitment into hex sockets. The polished chromium finish reduces surface corrosion and simplifies maintenance, while the compact shape makes it convenient for workshop storage and mobile tool kits.

Suitable for

• Automotive repair and mechanical maintenance
• Assembly of machinery and equipment
• On-site service and mobile tool kits
• Hobby and DIY projects requiring 17 mm hex turning

Key specifications

• Tool type: single-piece hex key
• Size: 17 mm (metric)
• Material treatment: quenched and tempered steel
• Surface finish: polished chrome
• Design: solid, one-piece construction for rigidity

How to use

Insert the 17 mm hex key fully into the hexagonal fastener to ensure full contact between the tool and the fastener faces. Apply steady torque, keeping the key aligned with the fastener axis to reduce the risk of rounding. For high-torque jobs, use controlled force and consider using proper leverage methods rather than excessive impact. After use, wipe the tool clean and store it in a dry place to maintain the polished chrome finish.

Usage recommendations

Use the Proline 17 mm hex wrench for properly sized hex fasteners only, avoid using the tool as a pry bar or hammer, and inspect the key for wear or damage before demanding tasks to ensure safe and reliable operation.
